THOMAS EGAN, 83., OF AMSTERDAM, NEW YORK.

CARDING-MACHIN E.

To'all whom it may concern:

Be it known that I, THOMAS EGAN, Sin, a citizen of the United States, residing at Amsterdam, county of Montgomery, and State of New York, have invented certain new and useful Improvements in Carding-Machines, of which the following is a specification.

The invention relates to such improvements and consists of the novel construction and combination of parts hereinafter described and subsequently claimed. Reference may be had to the accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Figure 1 of the drawings is a view in side elevation of a part of a wool-carding machine showing my invention applied thereto, the position of the main cylinder and the tumbler being indicated by dotted lines. Fig. 2 is a vertical section taken transversely of the feed-rolls, takein-roll, tumbler and main cylinder, showing the relative p0sitions of the same in the machine. Fig. 3 is a top plan View of the parts shown in Fig. 1. Fig. 4 is aview in side elevation similar to Fig. 1, with certain of the sprockets and gears removed for the purpose of illustrating the means for throwing into and out of mesh the feed-roll operating-gears. Fig. 5 is a vertical section of the same taken on the line 55 of Fig. 4 through the vertical plane of the axis of the stud upon which the eccentric sleeve is mounted, and of the axis of the bolt, whereby the bracket which carries said stud is attached to the frame of the machine. This invention relates to the class of card 5 Y ing-machines employing in combination with a main carding-cylinder, a pair of feed-rolls, and a take-in-roll between said feed-rolls and main cylinder, and the invention will be shown and described in its application to a type of such machine known as a woolen card. In machines of said type it has heretofore been customary to drive the take-in-- roll 'by means of a belt, and to drive the feed-rolls independently of the take-in-roll. In such machines the take-in-roll tends at times to become clogged, causing its driving- Specification of Letters Patent.

belt to slip and said take-in-roll to cease to rotate. In such cases, however, the feedrolls, being independently driven, continue to force the stock against the take-in-roll, causingthe same to pile up and become packed in between the take-in-roll and the feed-rolls, frequently resulting in injury to the machine and in a considerable loss of time in removing the stock thus accumulated in packed form.

The principal object of my invention is to insure in a machine of this type discontinuance of the operation of the feed-rolls whenever the operation of the take-in-roll is stopped for any reason, and to this end I have devised a positive driving means connecting together the take-in-roll and the feed-rolls.

Referring to the drawings wherein the invention is shown in preferred form, 1, rep resents the main cylinder, 2, the take-in-roll shown in the form of a bur-cylinder, and 33, the feed-rolls. Interposed between the take-in-roll and main cylinder I have shown the usual roll, 4, called a tumbler. Fixed upon the shaft, 5, of the take-in-roll is a pinion, 6, meshing with a gear, 7, rotatively mounted upon a stud, 8, projecting from the frame, 9, of the machine. In fixed relation to said gear, 7, is a sprocket-wheel, 10, connected by a chain, 11, with a sprocket-wheel, 12, rotatively mounted upon a stud projecting from the frame of the machine. A pinion, 13, in fixed relation to said sprocketwheel, 12, is adapted to mesh with a gear, 14, fixed upon the shaft, 15, of the lower feed-roll, the shafts of said feed-rolls being connected by intermeshing gears, 16, in the usual manner. lower may be transmitted in any known manner to any one of said gears, pinions 0r wheels, as, for example, through the belt-pulley, 17, which is fixed to the sprocket-wheel 10.

The tumbler, l, and main cylinder, 1, may be driven in the manner usual in machines of this type.

By means of the gears, pinions, sprockets and chain above referred to, it will be seen that the take-inroll, 2, is positively connected with the fecd-rolls,.3, so that said feed-rolls can operate only when the take-inroll is operating. Should the take-in-roll, 2, become clogged and stopped, the feedrolls, 3, thus also necessarily stop and cease to feed the stock to the take-in-roll, thus avoiding the piling up of stock between the feed-rolls and take-in-roll, and accomplishing the purpose of the present invention.

In machines of this type it is desirable to provide means for from time to time changing the speed of the feed-rolls relatively to that of the take-in-roll, and it is also desirable to provide means for quickly connecting and disconnecting the feed-rolls from the driving-mechanism therefor. I have therefore provided means for quickly moving the pinion, 13, into and out of engagement with the feed-roll operating-gear,

14, and also for permitting the pinion, 13, to be replaced from time to time by pinions of different sizes. The mechanism whereby this object is accomplished is more particularly shown in Figs. 4 and 5. The pinion, 13, and sprocket-wheel, 12, which are in fixed relation to each other are rotatively mounted upon a sleeve, 19, through which a supporting-stud, 20, extends eccentrically. The stud, 20, projects laterally from a bracket, 21, mounted upon the frame, 9, of the machine by means of a bolt, 22, passing through a slot, 23, in said bracket, and a locking-nut 24. The eccentrically mounted sleeve, 19, is rotatively adjustable upon the stud, 20, and is adapted to be locked in adjusted position by means of a nut, 25, on the outer end of said stud, whereby the sleeve is clamped against the bracket 21. When the nut, 25, is loosened rotative adjustment of the eccentrically mounted sleeve, 19, can be accomplished in any known manner, as by means of a handle 26. The adjustment of the bracket, 21, permitted by the slot, 23, permits the stud, 20, and sleeve, 19, to be located nearer the axis of the gear, 14, when the pinion, 13, is to be replaced by a smaller pinion, or at a greater distance from the axis of the gear, 14, when the pinion, 13, is to be replaced by a larger pinion. What ever may be the size of the pinion, 13. how ever, it can be quickly thrown into or out of engagement with the gear, 14, by a rotative movement of the eccentrically mounted sleeve 19.

By the term take-in-roll, I refer to a roll having the function of what is commonly known in the art relating to machines of this class as a bur-cylinder or a licker-in.

The gear, 7, sprocket-wheel, 10, chain, 11, sprocket-wheel, 12, and pinion, 13, form a train of speed-changing positively-interengaging driving-elements interposed between, and connecting together, the gear-wheel on the feed-roll with the gear-wheel or pinion on the take-in-roll, whereby the object of my invention is accomplished, while the proper reduction in surface speed of the feed-rolls from that of the take-in-roll is secured.
